1.4 Wood forming

Question 1

What are the 2 wood forming processes

Answer 1

Lamination, steam bending

Question 1

Name two methods to create a curved laminate form.

Answer 1

Vacuum Bagging, Clamping(1 / 2 former)

Question 2

Name one additional resource required for each of the stated methods.

2 Formers

Vacuum Bag

Answer 2

Clamps

Valve/Pump

Question 3

Describe one advantage for each of the stated methods.

Vacuum

Clamping

Answer 3

Ensures that there is no air gaps with even pressure

Not energy demanding / noisy

Question 4

State two wood or wood-based materials that could be laminated against a former/s.

Answer 4

Ply / Wood strips

Question 5

Describe one characteristic of using each of the stated materials.

Ply

Wood strips

Answer 5

More flexible and thick, less steps and available

More attractive, More brittle

Question 6

Identify a suitable adhesive to be used in the forming process.

Answer 6

PVA glue

Question 7

Outline how you would prevent the laminates from sticking to the former/s.

Answer 7

Separate the layers with a polythene sheet

Question 7

State two risks to worker safety when handling and then forming steam bent timber.

Answer 7

Burning risk
Large forces risk (Could Snap)

Question 8

Steaming timber at 100 degrees can take 1 hour for every 1” of timber thickness but the timber also needs to dry while it is clamped. How does this compare with lamination processes?

Answer 8

Steam Bending takes longer to dry (2-3 days)

Question 9

Describe 2 characteristic of steam bent timber.

Answer 9

Has usage in water (No Glue)
More sustainable
Stronger
Less Wastage
More attractive surfaces
Can lead to warping or splits
